GeForce 9500 GT 1GB GDDR3 vs GeForce GTX 650 Ti

Intro

Compare those specs to the GeForce GTX 650 Ti, which uses a 28 nm design. nVidia has clocked the core speed at 928 MHz. The GDDR5 memory runs at a frequency of 1350 MHz on this specific model. It features 768 SPUs as well as 64 Texture Address Units and 16 ROPs.

GeForce GTX 650 Ti		110 Watts
	Difference: 60 Watts (120%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 Ti will be 238% quicker than the GeForce 9500 GT 1GB GDDR3 in general, because of its greater data rate. (explain)

GeForce GTX 650 Ti		86400 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 60800 (238%)

Texel Rate

The GeForce GTX 650 Ti will be much (about 575%) more effective at AF than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 50592 (575%)

Pixel Rate

The GeForce GTX 650 Ti should be a lot (about 237%) more effective at FSAA than the GeForce 9500 GT 1GB GDDR3, and also able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 10448 (237%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
